SAFE CONSTRUCTION.

Application filed April 4,

To all whom it may concern:

Be it known that we, GUs'rAvE M. GOLD- SMITH and CARL BARTELS, citizens of the United States, residing at Hamilton, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Safe Constructions, of which the following is a specification.

This invention relates to safe construction, and more particularly relates to burglar-proof safe doors made up of a plurality of-plates or sections secured together, one or more of the plates or sections having special characteristics, such as being-highly resistant to drills, or to torches, or the like; and the principal object of our invention is to provide a construction for safe doors in which these plates and sections are secured and held together in such a way that the structure is thoroughly proof against penetration and entry by means of a torch and drill, or the like, and inwhich the plates or sections are held securely and firmly against bodily removal under attack. A

" further object of our'invention is to provide a safev door construction in which materialhaving special characteristics, such as being highly resistant to drill or torch, or to both,

' is so incorporated that it is substantially our. invention may be had, attention is hereby directed to the accompanying drawings,

forming a part of this application, and illustrating certain possible embodiments of our invention. i I

Referring to the drawings, Fig. 1 is a diagrammatical front viewof a safe door; Fig. 2 is a perspective view of a section of the door, the door being shown broken away step by step tomore clearly show the construction; and Fig. 3 is a sectional view of the door. Similar reference characters refer able.

to similar parts throughout the several views of the drawings.

Referring to the drawings, there is shown in Fig. 1, a safe door 1 and its vestibule 2, the door being supported by the usual crane hinge 3. As shown, a metal-section 4 (which may be a casting of suitable material, such as steel,) constitutes the body of the door and includes the front and jamb' portions and the outer bolt frames 5. Section 4 has a central cavity, as shown, the side walls of which are stepped inwardly toward the front of the door to form shoulders which abut against plates seated in the cavity. In the cavity are placed a plurality of plates which extend in the plane of the door, and

at least one of these plates is preferably-of material having special characteristics, such as being highly resistant to drill or torch, or to both drill andtorch, which is prefer- A plurality of plates 6, of suitable material, which may be openhearth steel, are placed in the front portion of the cavity,

and may be secured to the body 4 and to each other by suitable screws, such as 7. In the cavity and immediately behind plates 6' is a plate 8 of material having special characteristics, such as high drill or torch resistance, or both. The body 4 may be formed to have shoulders or ledges 9 which abut the forward edge portions of section 8. Section 8 is held in place by means of one or more keystrips 10 which are seated in a recess or groove 11 provided therefor in the body 4, and which extend beyond the groove 11 and overlap and abut against the rear edge portions of the section 8. The key strip or strips 10 are preferably of material I having special characteristics, such as being highly resistant to drill or torch, or to both. Also to the rear of section 8 there may be placed in the cavity a plurality of other plates 12 of suitable material, such as openhearth steel, and these plates may be secured together with suitable screws, such as 13. These plates, however, may be of material having the special characteristics, such as high drill or torch'resistance. The rear most of these plates 12 may overlap the key strip or strips 10 on the rear, and if the 'key'strip is of suitable material, the plate and strip may be secured together by 'a screw 14. The inner bolt frames 15 for bolts 16 may, if desired, be formed integral with this rear steel plate. It will be noted that the section 8 has no screws in it and at the same time it is held in place securely and firmly against removal either rearwardly or forwardly.

Preferably, the body -lis formed with a groove 17 extending completely about its jamb portion, and one or more strips 18 of material having special characteristics, such as high resistance to drill or torch, or preferably to both, are fitted into this groove, but leaving enough of the groove vacant at its outer end to enable one or more strips 19 of suitable material, such as copper, to be positioned in this part of the groove to cover the strips 18 of the special material and to hold them in position. A lip or flange 20 may be formed in body l at the outer edge of groove 17 to aid in retaining the strips 19. and 18 in place in the groove. Preferably, the strips 10 and 18 extend into the jamb portions of body 4 sufficient distances. to overlap each other, with the result that the jamb portions of the body 1 incorporate material having the special characteristics extending substantially across these jamb portions in the plane of the door. The plate 8 extends across the door portion between the jamb portions, and thus the door incorporates the special material substantially coextensively in its plane and presents extremely high resistance to penetration by drill and torch at every point.

As many changes could be made in the above constructionand as many apparently Widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

What we claim. is
